'valid_min', 'valid_max', and 'valid_range' question

I am currently writing some programs that 'pack' floating point
values into BYTE and SHORT variables, but keep the 'scale_factor'
and 'add_offset' attributes as FLOAT.

My question is about the valid_{min,max,range} attributes...

The NetCDF documentation says that 'valid_min', 'valid_max',
and 'valid_range' should be the same type as the packed variable,
but I'm finding it convenient to make them the same type as the
'scale_factor' and 'add_offset' attributes...

It would seem to me that the appropriate data-type for these
attributes depends on whether one wants to do range-checking
before or after scaling the variables..

How are other NetCDF developers handle this issue ?

Thanks,

-Randy
